Abstract: A press for separating solids from liqs. by filtration consists of a central core, side plates and filter plates. The assembly is held by bolts by which the gaps between the faces of the core and plates can be adjusted. The filter plates have grooves and filtrate collection basins connecting to filtrate outlet pipes. Each face of the core is covered by an impermeable flexible membrane held by a ring on the edge of a movable circular frame which is mounted in a groove in the core opposite the rim of the filter plate. The bottoms of the grooves are connected by a pipe to an inlet of a liquid under press, and joints ensure fluid-tightness. Return springs distributed around the core are connected to eyebolts in the core and movable circular frames. The centre of each membrane is held tight on the face of the core by a collar and a hollow bolt. A feed pipe for liq. to be filtered passes through the hollow bolts and is connected to an inlet pipe. A further feed pipe conected to another inlet pipe can admit a fluid under press. behind the membranes. The side plates carry rollers which transport endless filter cloths by perforations registering with teeth on the driven rollers. Plates bear against the filter cloths to srape off filter cake on to a discharge belt. The filter cells formed between the membranes on the faces of the core and the surfaces of the filter plates by the frames are closed and opened by fluid press. and springs, and the filter cake is removed, automatically, giving simpler operation, and higher productivity and yield than conventional filter presses and the cake is thinner, requiring less operating press.

Patent FR-2274169-A1 (FR)
IPC: H04B10/40
Filed: 1975-06-06
Abstract: 1465329 Optical communications system POST OFFICE 6 June 1974 25166/74 Heading G1A The bandwidth of an optical communications system is controlled by means of a section of liquid filled dielectric optical waveguide 8, silicon tube filled with carbon tetrachloride, disposed in a temperature maintaining device 9. The temperature of the waveguide determines the number of transmission modes allowed. The temperature is retro-actively controlled with respect to a comparison between the ratio of two pre-selected modes on the received bandwidth and a predetermined reference signal. The optical communications signal uses an optical carrier signal into which an analogue signal having a bandwidth to be controlled, is modulated. In a repeater circuit, Fig. 2, the light signal enters the system via the optical waveguide 7, passes via a section 8 of a liquid cored dielectric optical waveguide and is received by a photodiode detector. The detectors output is amplified and is passed to two tuned circuits 13, 14 which are tuned to a frequency W 2  corresponding to the half power point of the cut-off edge of the required bandwidth and a frequency w 1  corresponding to the flat response region of the desired bandwidth. The levels L 1 , L 2  of the frequencies W 1 , W 2  are measured by level detectors 15 and 16 and the results are passed to a divider 17 which produces a signal representative of L 1 /L 2  that is fed to an analogue comparator 18. There it is compared with  a reference signal, corresponding to the desired ratio value. The resulting error signal from the comparator 18 is used to reset the temperature of the oven 9 via a temperature reset unit 20 and a servo temperature controller 21. The repeater circuit also comprises a driver circuit 22, connected as shown, which powers and modulates a laser source 23 which is optically connected to an output dielectric waveguide 26. The number of modes excluded by this arrangement is determined by a second oven 25, operating at a pre-set temperature, enclosing a section of liquid cored dielectric waveguide. An arrangement involving a series of repeater circuits is also disclosed.

Title: Engine powered from solar energy - has freon filled solar panels with cold water heat exchange systems
IPC: F01K13/02
Filed: 1975-07-11
Abstract: The solar heat engine (5) uses Freon (RTM) as a working fluid which receives heat from the heat exchangers (12, 15). One heat exchanger (12) is supplied with heat from water which has been heated by one Freon filled solar panel and circulated by pump (3). The other heat exchanger (15) receives heat from another Freon filled silar panel (2). The Freon (RTM) leaving the engine (5) flows into the heat exchanger (18) where it releases its residual heat. It is then pumped (20) to the constant head tank (21) and returns to the heat exchanger (12). The Freon cooling heat exchanger (18) is cooled by the water system circulated from the old tank (28) which loses heat at night due to the water flowing through the radiator (31) which radiates heat to the atmosphere.
